EXPANDED-METAL IANUFACTRE.

Application filed July 27,

y vented a new and useful improvementl in Expanded-Metal Manufacture, of which the following is a specification.

The invention relates to methods and apparatus for expanding metal sheets or strips of the thicker gauges for making road mesh or the like; und the objects of the improvementA is to provide a continuous method an'l apparatus for producing an expanded mesh with the adjacent bonds reversely corrugated, and with the connecting bars either stretched or merely bent, as may he desired.

Road mesh need not be provided with longitudinal beads or ribs, which if present in a sheet could loe engaged by guides for expanding the mesh; and the present improvement involves a reverse corrugation of alter nate rows of bonds, and the engagement of certain rows of bonds hy diverging guides for separating the bonds to form the mesh.

Apparatus which may be employed for expanding road mesh. by the new method, is illustrated in the accompanying drawings, forming part hereof, in which- Figure l is a diagrammatic side elevation, in two sections, of the improved apparatus, showing rolls of equal diameter;

rhe improved apparatus includes a series ofright sets, more or ieee. of corrngating rolls 1, 2, 3. a. 5. G. 7 and 8: and correspond ing guides la. Qa, 3".. 4, 5, o, 7 and 8". in front ofthe rst set of corrugating rolls may be located a set of slittingI rolls 9, in rear section on line how s ged a m (mes o'n in 80 i meter ongxtndmal cated :s of a L a b ams QN" mirth V and fof each Likewise the third guides shown in Fig. Xlll', re duplicated in the successive guides, excepting only that the lateral distance between the guide bars is increased to the eighth guide 82, wherein the maximum interval between Guide bars 8a is reached, as shown in Fig. l VI,

The intermediate bars 'in each guide are longitudinally arched so as to equalize the length of the diverging liars, as shown in a general way in Figs. l and ll; and when the ull lateral expansion of tlxe sheet, has been made, as by the eighth' set of rolls and guides, the flattening rolls 10 act upon the sheet to bring the corrugated bonds and inclined bars into the same plane, as shown in Fig. XVH, following which the straighten ing rolls 1l serve to smooth the expanded sheet in well known manner.
